Bandwidth considerations in miniaturized rectangular dielectric resonator antennas: experimental validation

Abstract

In this thesis, an issue of bandwidth is considered in a rectangular dielectric resonator antenna (RDRA). Two techniques (merging of modes and stacking) of bandwidth im- provement are introduced with miniaturized resonator. Single narrowband in RDRA is also introduced and investigated. Dual narrowband is proposed in a L-shaped DRA. It is compact structure as compared to a conventional DRA structure.
